This kind of fuel includes upright fuels over 6 ft.

• A. Subsurface
• B. Surface
• C. Aerial
• D. Ground fuels

Answer: (C)

In wildfire fuel classification, fuels are grouped by their position relative to the ground. Upright fuels that exceed about 6 feet are categorized as aerial fuels. This includes canopy and tall branches that stand above the ground and can carry fire rapidly through the crown, especially under windy, dry conditions. Subsurface fuels are below ground, and surface fuels lie on or immediately near the ground and aren’t tall. Ground fuels refer to fuels in or on the forest floor, not tall vertical structures. So the description of tall, vertical fuels over 6 feet fits aerial fuels.
